To all whom it may concern Be it known that I, GENTRY LHKROWSEY, a citizen of the United States of America, a resident of Quincy, in the county of Adams, State of Illinois, have invented certain new and useful Improvements in Apparatus for Treating Hydrocarbon-Oils, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to an apparatus for use in converting hydrocarbon oils of high boiling points into hydrocarbons of lower boiling points of the same series, the invention having for its object to provide a mild cracking operation and produce a distillate preferably of from 48 to 50 gravity Baum.

Figure I is a view in elevation, partly in vertical section, of my apparatus, the furnace housing the still portion of the apparatus being omitted.

Fig. II is a longitudinal vertical section taken on line 11-11, Fig. IV, showing the still in side elevation and the furnace in section.

Fig. III is a longitudinal vertical section taken on line IIIIII, Fig. IV centrally of the still and its furnace.

Fig. IV is a cross section through the still and its furnace.

In the drawings, A designates the still of my apparatus as a whole, this still comprising bottommanifolds 1, a top manifold 2 and series of connecting pipes 3 providing communication between said bottom manifolds and said top manifold. There are preferably two of the bottom manifolds 1, extending longitudinally of the apparatus and spaced apart from each other, as seen most clearly in Fig. IV. The connectin pipes 3 are inclined upwardly from said lower manifolds to the upper manifold.

4 designates an oil supply pipe for delivering oil into one of the lower manifolds 1,--

and 6 is a steam conducting pipe through which steam is admitted to said manifold, the flow through these pipes being controlled by valves 5 and 7. The said pipes 4 and 6 and their valves are duplicated for supplyin "oil and steam to the second lower manifol 1.

8 designates a distillate conducting pipe leading from the upper manifold 2, first in a downward course at the forward end of the still and then in an upwardly and rearwardly inclined course to the rear of the still, the inclined portion of said pipe preferably passing between the series of pipes 3 providing communication from the lower manifolds to the upper manifolds of the still.

9 designates a primary condenser coil with which the upper end of the distillate conducting pipe 8 communicates. This coil is connected to the distillate conducting pipe at its lower end and its discharge end is located uppermost. The coil 9 is arranged within a condenser pan 10 having water inlet and overflow connections 11 and 12 which provide for a continuous circulation of water through the pan 10 to constantly exert a cooling influence of the primary condenser coil.

13 designates a secondary condenser coil, the upper end of which has communication with the upper end of the primary condenser coil by a connecting pipe 14, the said secondary condenser coil being arranged in a condenser pan 15 having water inlet and overflow connections 16 and 17. At the discharge end of the secondary condenser coil is a valve 18.

19 designates a separator into which the condensed distillate is delivered from the secondary condenser, this separator being provided with a suitable gage 20 to constantly indicate the quantity of condensed distillate in the separator, and the separator has connected to it an outlet pipe 21, having a valve 22, through which the contents of the separator maybe drawn during the operation of the apparatus.

23 designates a gas conducting pipe leading from the separator 20. This gas conducting pipe is provided with a valve 24 and leads to a compressor 25. The said compressor serves to draw the permanent or incondensible gases from the separator 20 through the pipe 23 and deliver them through a pipe 26 to a dome 27'surmounting the upper manifold 2 of the still A. The said pipe 26 is provided with a suitable valve 28"%.1

B designates a furnace within which the tillate conducting conduit leading from said still to said primary condenser, said conduit being so connected to said primary condenser condensers arranged in series,

. to said pr mary condenser,

as to provide for simultaneous delivery of vapors of distillation fromthe still to the primary condenser and reflux flow of condensate of heavy vapors of distillation from the primary condenser to said conduit, and means for heating said conduit to vaporize and crack the condensate of heavy vapors delivered thereto from the primary condenser. 2. An apparatus of the character described comprising a still, primary and secondary a distillate from said still said conduit being so disposed as to prevent flow of condensate therethrough to said still and being so connected to said primary condenser as to provide for delivery of vapors of distillation from the still to the primary condenser and reflux flow of condensate of heavy vapors of distillation from the primary condenser to saidconduit, and means for heating said conduit to vaporize and crack the condensate delivered thereinto from the primary condenser.

3. An apparatus of the character described comprising a still, primary and secondary conducting conduit leading condensers arranged in series, a distillate conducting conduit leading from the top of the still to said primary condenser, said conduit being in part located below the point of its connection With said still to prevent the flow of condensate from the conduit to the still and being so connected to said primary condenser as to provide for simultaneous delivery of vapors of distillation from the still to the condenser and reflux flow of condensate v of heavy vapors of distillation from the primary condenser'to said conduit, and means for heating said conduit to 'vaporiz'e and crack the condensate delivered to the conduit from the primary condenser.

4. In an apparatus of the character described comprising a still, primary and secondary condensers arranged in series, a distillate conducting conduit leading from said still to said primary condenser, said conduit located beneath the point of being in part to said still to prevent flow of its connection condensate through the conduit to the still and connected to the bottom of said condenser to permit reflux flow of condensate of heavy vapors of distillation from the primary condenser to the conduit, and means for heating said conduit to vaporize and crack the condensate of heavy vapors.
